Whether they are seasonal or chronic, respiratory allergies or allergic rhinitis poison the lives of a growing number of people. Allergies are exaggerated reactions of the immune system that cause inflammation in the sinuses, nasal congestion, watery eyes, and a wide range of other symptoms. They complicate the lives of those who suffer from them and can manifest year-round, not just in summer. Some symptoms can be alleviated with antihistamine herbs (reduce the allergic reaction), anti-inflammatory herbs, emollients of the respiratory system (reduce irritation) or astringents (tighten the tissues therefore reduce secretions). As for any inflammatory problem, we must treat it over a long period and adopt a healthy lifestyle.
